The contact owns a 2023 Mazda CX-5. The contact stated that while the temperature was 45 degrees or lower, the vehicle failed to start properly, and the engine failed to warm up properly. The coolant light was illuminated, and the engine temperature gauge failed to rise above COLD. The vehicle occasionally failed to start or while started and driving at various speeds, the vehicle stalled while and engine temperature failed to reach the normal operating temperature. The check engine light was illuminated. The contact would shift to SPORT Mode to prevent the cylinder activation from occurring and causing the vehicle to stall. The contact stated that the failure persisted, and the vehicle was hesitating while driving in temperatures of 50 degrees or less. Additionally, the key fob intermittently failed to unlock the vehicle. The contact stated that the vehicle failed to start and had to be towed. The contact stated that during the recent failure, the battery was disconnected, and the vehicle was towed to the dealer to be diagnosed. The contact stated that the key fob battery had been replaced 6 times; however, the failure persisted. The vehicle had not been diagnosed or repaired for the engine failure. The contact called another dealer, J. Allen Mazda (15150 Airport Rd, Gulfport, MS 39503); however, only an appointment to inspect the vehicle was made but the vehicle was not yet inspected. The manufacturer was made aware of the failure and a case was filed. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 4,000.

I love this car, but it has a bad habit, the vehicle accelerates on its own. If you take your foot off the gas, the car will intermittently lurch, almost jump forward. I-??ve learned to deal with this by simply keeping a strong push on the break, but it is definitely is an issue. Another issue I-??m having is the back lift gate. I-??ve been told that the sensors are on each side of the gate and perhaps when drying the vehicle, I touch them? they run along each side of the liftgate fully visible. I have 17,000 miles on my car right now and when the lift gate opens closes it stops halfway and it beeps. I then have to push it down to close. I took it to the dealer and they say it will cost me if they have to check the sensors. This is extremely annoying to have an automatic lift gate, and I have to push it down myself.

Brand new 2023 Mazda CX-5 with 150 miles on it experienced unintended acceleration while braking. Pulled into a parking spot with my foot on the brakes but the car didn't stop & even accelerated over a sidewalk and into a building. I experienced a bruise from the seatbelt. Airbags did not deploy. Someone could have been killed if they had been on the sidewalk. Car is currently at an auto body shop to fix the cosmetic damages, and once released, will have the car towed to our local Mazda dealership/service center to get the car inspected. In doing research on NHTSA's website, at least 4 vehicles (2-2023 Mazda CX-5s and 2-2023 Mazda CX-30s) have experienced this issue. Mazda needs to recall these vehicles and investigate.

The power liftgate on the 2023 Mazda CX-5 SUV closes with sufficient force that the vehicle owner's manual warns of possible serious injury or even death, and cautions the operator to be sure that people or objects are not in the way of closure. However, the actual design of the overall system permits accidental closure by way of the key fob even when the operator is out of sight of the vehicle. This effectively renders the warnings meaningless, and disregards the safety of people or objects that might be in the way. The vehicle electronics/computer system uses dual purpose switches in or on the vehicle to activate the liftgate; if closed, a press of the switch will unlock and open it, and if open, the same switch will close and lock it. The system also provides the same feature with an exposed, raised button on the key fob which can easily be accidentally pressed to activate closure. Who then assumes liability for the possible resulting tragedy? During my first month of ownership (April 2023), I have experienced the liftgate opening by accident at least twice and it obviously could have been both opened and closed numerous times by accident totally without my knowledge. In a similar fashion, I have experienced the susceptibility of the other fob switches to accidental activation; the car has been locked by accident as least once, and the horn accidentally activated at least three times when I have been inside the house while the car is out of sight in the garage and the key fob was in my pocket. I am obviously making the reasonable assumption that accidental pressure on the various fob switches is the cause for activation. The attached PDF document describes in more detail some of the hazards posed by the existing design, and possibly applies to other car makes and models
